A synergetic of Amine-functionalized bimetalliczeolitic imidazolate frameworks as efficient catalyst for the chemicaltransformation of CO2 |
| 초록 |
Amine-functionalizedbimetallic zeolitic imidazolate framework-8 (Co/Zn-ZIF-A) with was synthesizedvia a post-synthetic modification to utilize as a heterogeneous catalyst forthe synthesis of cyclic carbonates from CO2 and epoxides. Co/Zn-ZIF-Awith the highest contents of amine (Co/Zn-ZIF-A) exhibited superior catalyticactivity compared to that of pristine Co/Zn-ZIF for CO2cycloaddition reaction and achieved an excellent conversion of epichlorohydrin withhigh selectivity without co-catalyst and solvent under mild conditions. Theacid-base synergistic effect of Co/Zn-ZIF-A derived from the combination ofbimetallic systems consisting of Zn and Co as Lewis acid sites and the abundantLewis bases sites of -NH2, -NH groups enabled a high epoxideconversion with an excellent product selectivity. Co/Zn-ZIF-A catalyst showedgood reusability without obvious loss in catalytic activity during fiverecycling runs, which was also confirmed the structural stability. |
